<p>A wheel chair (1) with an auxiliary power which comprises an electric motor (32), a potentiometer (27) as a means for detecting human power exerted on a wheel (2), and a controller (31) as a means for controlling the electric motor (32) in accordance with the detected human power, and in which an auxiliary power corresponding to a magnitude of the human power is exerted on the wheel (2) to rotatingly drive it, wherein a time attenuation factor of the auxiliary power is preset to be inversely proportional to the human power. Since a coasting amount of the chair (1) is limited to be smaller than, for example, feeble movements in a room, it is possible for the chair to ensure small movements with a sharp turn in the room and an adequate coasting in outdoor travelling to enable comfortable travelling on a flat ground and easy climbing of a steeply sloping road with reduced occupant's physical load.</p> |
